Abstract
THE researches lately published by the Drs. Sarasin upon the anatomy of the Echinothuridæ, render a careful reconsideration of the types of Asthenosoma collected by the late Sir Wyville Thomson, during the voyage of H.M.S Porcupine, absolutely necessary in my opinion. The species were described in the Philosophical Transactions for 1874. I shall be much obliged if information can be sent me regarding the whereabouts of the specimens which were figured by Wild, i.e. the type-specimens of Calveria (Asthenosoma) hystrix, Wy. Th.; C. (Asthenosoma) fenestrata, Wy. Th.; and Phormosoma placenta Wy. Th.
